DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for draining granular material, and a rice-free rice making machine provided with the device.

[0002]

2. Description of the Related Art Conventionally, rice is cooked without grinding by providing a rice washing section and a drying section, washing rice that has been polished and then removing moisture adhering to the surface of the rice in a short time. 2. Description of the Related Art Non-washing rice making machines for producing possible so-called non-washing rice are known.

[0003] Unwashed rice must have a good texture and a good preservability, and for that purpose, the lipids contained in the ariuron layer of brown rice that cause the smell of bran during cooking and discoloration during preservation. It is necessary to remove such residues as possible.

Further, in order to improve the preservability, the moisture content of rice must be suppressed to, for example, 16% or less. Therefore, in the above-described conventional rice-free washing machine, ariuron residues are thoroughly removed in the washing section. After washing off, they are quickly dried in the drying section.

[0005] Therefore, in order to perform drying effectively, a draining step is generally provided before the drying step. In the draining step, a draining device X as shown in FIG. 7 is used. ing.

That is, in a high-speed rotating centrifugal dewatering tank 200 provided with a large number of through-holes 100 on the peripheral wall, a washing rice supply cylinder 400 provided with a screw blade 300 rotating differentially with the dewatering tank 200
The rice 500 supplied from the washing rice supply cylinder 400 is transferred upward by the screw blade 300 while being centrifugally dewatered, and scattered outside from the centrifugal dehydration tank 200, and the scattered rice 500 is illustrated. It is configured to be received by a net or the like and transported to the subsequent drying step.

[0007]

However, in the case of using the centrifugal dewatering tank 200 described above, although the drainage can be performed in a short time, the rice collides with the peripheral wall of the centrifugal dewatering tank 200 in order to rotate the rice at high speed. In some cases, cracks and the like were caused by the collision of rice and rice, causing damage.

[0008] When such cracked rice is dried and shipped without washing, there is a problem that when cooked, the rice becomes softer than necessary and becomes extremely poor in texture when cooked. Was.
